中文摘要：基于生态安全格局进行国土空间生态修复关键区识别是新时期平衡环境保护与社会发展的重要手段.本研究以环太湖城市群为研究区,从结构和功能两方面综合确定生态源地,在构建阻力面的基础上利用最小累积阻力模型识别生态廊道并耦合景观生态风险评价来确定研究区每条生态廊道的适宜宽度,通过电路理论识别重点修复区,最终构建"六区四带"的生态安全格局并进行分区管控.结果表明:环太湖城市群的32处生态源地呈现"东多西少、山湖相连"的空间格局,70条生态廊道集中分布于西部和中部,绝大部分生态廊道的适宜宽度在1500-2000 m;国土空间生态修复区集中存在于太湖东部、长兴县和溧阳市内;根据研究区特点和修复区实际情况,本研究提出保护核心生态源地、优化并修复重要廊道、合理规划生态夹点和障碍点用地等具体保护修复措施.

外文标题：Identification of key areas for ecological restoration of territorial space based on ecological security pattern analysis:A case study of the Taihu Lake city cluster

外文摘要：The identification of key areas for ecological restoration of national land space based on the ecological security pattern is an important way to balance environmental protection and social development in the new era.With the Taihu Lake city cluster as the study area,we identified the ecological source from both structural and functional aspects,and used the minimum cumulative resistance model to identify the ecological corridors on the basis of constructing the resistance surface.Coupled the landscape ecological risk evaluation,we determined the appropriate width of each ecological corridor in the study area,identified the key restoration zones through the cir-cuit theory.Then,we constructed the ecological security pattern of"six zones and four belts"and controlled by zoning.The results showed that the 32 ecological source areas in the Taihu Lake city cluster presented a spatial pat-tern of"more in the east and less in the west-mountains and lakes are connected"and 70 ecological corridors were concentrated in the west and the center.The suitable width of most of the ecological corridors was 1500-2000 m.The ecological restoration zones of the national land space were concentrated in the eastern part of the Lake Taihu,Changxing County,and Liyang City.According to the characteristics of the study area and the actual situation of the restoration area,we proposed specific protection and restoration measures,such as protecting the core ecological source,optimizing and restoring the important corridors,and reasonably planning land use of the ecological pinch points and obstacle points.
